I've had Pentax SLR cameras and more recently I got a Fujifilm mirrorless which I still have. I enjoy photography and one of my requirements is the ability to generate RAW files for editing.
I read that Nexus 5x was one of 5 cameras that can generate RAW files so I got a third-party package, FV 5, and went to a nearby museum. The low-light performance was outstanding.
That room has always been hard for me to shoot because it's dimly lit. The museum doesn't allow flash shots. The Nexus 5x camera did great.
